Pure Audio is an innovative high-end delivery format based on standard Blu-ray technology;developed by MSM-Studios in Munich in collaboration with Lindberg Lyd of Norway. The diskscarry high-resolution music in stereo and multi-channel surround sound with up to 24-bitresolution at sampling frequencies of up to 192KHz. These audio-oriented disks can be playedon any commercially available Blu-ray player. The format allows artists to enhance their musicreleases with visual content and bonus features, but the focus remains on the music itself.With 33% of the population already having Blu-ray players at home, Bert van der Wolf ofNorthstar Recording Services wanted to make “The Spirit of Turtle” collection available to thisexpanding audience, particularly those dedicated to listening to high fidelity sound. Pure AudioBlu-ray offers the consumer the high quality musical listening experience intended by the artistand production team, on par with the actual studio master. “The Spirit of Turtle” is the first Dutchproduction to be released on this exciting new format.Wisseloord Studios, in the Netherlands, is one of the few facilities in Europe offering creativeauthoring services for Pure Audio Blu-ray releases. Wisseloord is a high end audio facility,established in the 1970’s and rebuilt in 2010 to meet the highest technical standards of todayand the foreseeable future. They offer recording, mixing, and mastering in-house, with a focuson high resolution audio. With the addition of their media department, including authoring andcreative services, the team at Wisseloord is capable of taking on projects for nearly any releaseplatform, Pure Audio BluRay being an exciting new option for music content producers.Wisseloord is also a member of the Pure Audio Group which is made up of a group ofinternational music professionals who share their expertise and enthusiasm in support ofbringing high resolution audio into the living room through the Pure Audio BluRay format.“The Spirit of Turtle” is an ultimate show case initiated by HQ|NORTHSTAR, a brand directlyevolved from the audiophile Turtle Records® label, in collaboration with UK based DataConversion Systems. When Bert van der Wolf presented Wisseloord with the challenge ofdoing his first Pure Audio Blu-ray authoring for this ambitious project, the Wisseloord teamworked in conjunction with MSM-Studios, who have founded and developed the Java scriptingfor the advanced functionality of the new format. Screenless navigation, for example, was notforeseen in the original Blu-ray specification and is an important feature in Pure Audio Blu-ray.Pure Audio disks are driven by music rather than video content and screenless navigationallows the user to operate the disk without video menus just like a CD – an important feature forease of use and potential future implementation in the automobile industry.Of course, for users preferring navigation on a screen, the Pure Audio Blu-ray provides menusjust as on a video Blu-ray. These pop-up screens give information about the tracks, tracklengths, audio streams or additional information, such as production credits. Bonus featuressuch as video content, photo albums, biographical information, etc., can also be included. In thecase of the “Spirit of Turtle” release, the unparalleled audio quality and ease of use on the diskitself is supplemented with “mShuttle” technology: if your Blu-ray player is connected to yourhome network, you can use the browser application on your computer to access digital masterfiles in FLAC Format 24 bits/192kHz.HQ|NORTHSTAR’s stunning retrospective “The Spirit of Turtle” on Pure Audio Blu-ray, made inconjunction with Wisseloord Studios and the Pure Audio Group, is a prime example of how thisexciting new format can bring the home listening experience to a whole new level.
